LOW POWER LOW OFFSET
VOLTAGE QUAD COMPARATORS General Description
The AZ339 series consists of four independent precision
voltage comparators with an offset
voltage specification as low as 2mV. The input common mode
voltage range of these comparators includes ground, even when operated from a single power supply
voltage. Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply
voltage. The AZ339 series is designed to directly interface with TTL and
CMOS. The AZ339 series can be widely used in such applications as battery charger, cordless telephone, switching power supply, DC-DC module and PC motherboard.
